Inactive scheduler linkage

What causes this issue?

The link for scheduled processes in the workflow scheduler is not
active.
The workflow scheduler function in <LS>Environment, Health, and Safety
</>and <LS>Product Safety and Stewardship</> is used to schedule and
execute certain processes, such as actions or notifications. If a user
changes a process by, for example, adding a further action, this can
affect the schedule of the next execution of this process. The workflow
scheduler needs to be informed about the changes and checks and corrects
the next schedule.
